[0031] The lateral adjustment unit includes a second slide groove 603, a second slider 604, a first clamp 605, an anti-slip sheet 606 and a second clamp 607.

Through the sliding cooperation of the second slide groove 603 and the second slider 604, the lateral position adjustment of the first clamp 605 and the second clamp 607 is realized to adapt to shells of different sizes.

[0032] The longitudinal adjustment unit includes a movable plate 7, a third slide 701, a screw rod 702, a fixed plate 703, a motor 704, a third slider 705 and an electric push rod 901. The bottom of the movable plate 7 is overlapped on the upper surface of the support platform 602. The third slide 701 is provided on the upper and lower sides of the front of the movable plate 7. The length of the third slide 701 is less than the length of the movable plate 7.

A placement groove 301 is provided on the side where the first slider 3 of the left clamping mechanism and the first slider 3 of the right clamping mechanism are close to each other.

The cooperation between the guide block 601 and the guide rail 201 makes the first slider 3 more stable when moving, reduces vibration and deviation, and thus improves the clamping accuracy and stability.

[0035] Working principle: Place the pressure sensor housing to be pressed at an appropriate position on the support table 602 to ensure that the housing is aligned with the clamping mechanism. As needed, the electric push rod 901 drives the second slider 604 to move and adjust the position of the second slider 604 in the second slide groove 603, thereby changing the position of the movable plate 7 to adapt to housings of different widths. Start the motor 704, the motor 704 drives the screw rod 702 to rotate, and the third slider 705 drives the second clamping block 607 to adjust the position of the second clamping block 607 to move closer to the first clamping block 605 to adapt to the length of the housing. Start the cylinder 8 until the left and right clamping mechanisms are in contact. The cylinder 8 is connected to the first slider 3 through its output end. When the cylinder 8 is working, it pushes the first slider 3 to slide in a specific direction in the first slide groove 101. This sliding movement enables the left clamping mechanism and the right clamping mechanism to move closer or farther, thereby clamping or releasing the pressure sensor housing. During the clamping process, due to the meshing transmission of the gear 5 and the rack 4, the left clamping mechanism and the right clamping mechanism will open and close synchronously to ensure the accuracy and coordination of the clamping, and the cooperation between the guide block 601 and the guide rail 201 makes the first slider 3 move more smoothly, reducing vibration and deviation, thereby improving the accuracy and stability of the clamping.

[0036] After the pressing operation is completed, the cylinder 8 drives the first slide block 201 to work in the reverse direction, so that the clamping mechanism releases the shell and moves to the initial position. At this time, the operator can take out the pressed shell and prepare for the next operation.
